The present invention provides a heat dissipation device including (a) a baseplate, (b) one or more heat pipes in thermal communication with the baseplate, where the one or more heat pipes has one or more internal cavities, (c) one or more vapor chambers coupled to the one or more heat pipes, where the one or more vapor chambers has one or more internal cavities, where the one or more internal cavities of the one or more heat pipes and the one or more internal cavities of the one or more the vapor chambers are contiguous, where the one or more vapor chambers extends from the one or more heat pipes, and (d) one or more heat conducting fins coupled to the one or more vapor chambers, where the one or more heat conducting fins extends from the one or more vapor chambers.

Problems with Heat Dissipation

Recent advances in performance and capacity in electronic devices, (i.e., computer systems, computer components, processors, and computer devices) have led to an increase in total power consumption and special power density. In addition, the required I/O (Input/Output) pin density has also substantially increased due to wiring/interconnect densities. The increased I/O pin density has raised the loading pressure needed to securely seat these I/O pins. New fluidic thermal cooling advancements are needed to address the thermal challenges of electronic circuit devices while providing the increased pressure required to securely seat the I/O pins.

In a conventional heat pipe heat sink thermal solution, bends in a heat pipe may be required to fan out the heat from the device and to extend to fins. Bending the heat pipe may put stress on the heat pipe, which may damage the heat pipe. The bends put a compressive stress at an inner portion of the bend and tensile stress at an outer portion of the bend. If the bend is too severe, the stress may damage the heat pipe walls and any internal wick structure. Likewise, the gap created by the bend separates the heat pipe from the baseplate, preventing good thermal contact and thereby limiting heat transfer from the baseplate to the heat pipe in that region. A heat pipe is a heat transfer device that transfers heat by vaporizing water in one area of the heat pipe and condensing it at another. After condensing, the liquid is transferred back to the hot area of the pipe in any suitable manner, including capillary action, centrifugal force, or gravity. A wick structure may be used in the heat pipe to facilitate the capillary action.

Some vapor chamber baseplates could have support structures or posts but these could decrease the thermal transfer rate of the vapor chamber in critical areas. Traditionally fins are attached to heat pipes by edge bonding round heat pipes through a hole in the fins. This joint is difficult to manufacture and not reliable. The soldered edge could be discontinuous, thereby limiting thermal transfer anywhere there is a break.

Modern processors could require a large force placed on them by a cooling assembly to adequately engage the I/O pins of the processor. If the load exceeds a load threshold of a cooling component in the assembly, it could damage or destroy the cooling apparatus. For example, a load plate could crush heat pipes and vapor cambers, rendering them ineffective.

In an embodiment, the present invention circumvents this issue by soldering or brazing one or more straight heat pipe segments to one or more vapor chambers so that the one or more heat pipe segments do not have to be bent. In an embodiment, the attachment of one or more heat pipes to one or more vapor chambers is done by any method that produces a thermally conductive interface. Likewise, soldering or brazing the heat pipe onto the vapor chamber allows any attachment angle (e.g., even ninety degrees) without a gap being formed at the edge. In an embodiment, the one or more vapor chambers is soldered or brazed to the one or more heat pipes. In one embodiment, the method includes soldering or brazing the one or more vapor chambers to the one or more heat pipes.

In an embodiment, heat pipes are strategically located in critical cooling areas and islands, designed to take the load from a pressure plate and transfer it to the base plate, and are located in areas that do not need as much cooling. In an embodiment, one or more fins is bonded at a bent edge of the fin, onto the flat surface of a vapor chamber. In an embodiment, the present invention provides one or more islands, next to one or more heat pipes, where the one or more islands is designed to take the pressure directly from a load plate and transfer it to the baseplate, thereby bypassing the heat pipes.

Heat Pipe and Vapor Chamber

Referring to FIG. 1A and FIG. 1B, FIG. 1B is a cross-sectional view of FIG. 1A taken at cross-sectional line 3. In an embodiment, the present invention provides (a) a heat dissipating device 100, including one or more heat pipes 110 in thermal communication with a baseplate 180, where one or more heat pipes 110 has one or more internal cavities 115, (b) one or more vapor chambers 130 and 170 coupled to one or more heat pipes 110, where one or more vapor chambers 130 and 170 has one or more internal cavities 135, where one or more internal cavities 115 of one or more heat pipes 110 is contiguous to one or more internal cavities 135 of one or more vapor chambers 130 and 170 (heat dissipation cavities), where one or more vapor chambers 130 and 170 extends from one or more heat pipes 110, (c) one or more heat conducting fins 150 coupled to one or more vapor chambers 130 and 170, where one or more heat conducting fins 150 extends from one or more vapor chambers 130 and 170. In an embodiment, one or more fins 150 is soldered to one or more flat portions of one or more vapor chambers 130 and 170.

In an embodiment, one or more fins 150 is be soldered along a bent side edge 140 of one or more fins 150. In an embodiment, at least one of one or more heat pipes 110, and at least one of one or more vapor chambers 130 and 170 are hermetically interconnected and cooperatively form at least one sealed chamber. In an embodiment, fins 150 are bonded at a bent edge 140 of fin, onto the flat surface of a vapor chamber, thereby allowing for a more reliable bond to be made between bent edge 140 of the fin and the flat face of the vapor chamber.

In an embodiment, the present invention includes baseplate 180 with one or more islands 120 formed on one surface. One or more islands 120 may be configured to take compressive force applied to it by a load plate 160. In an embodiment, load plate 160 is a u-shaped channel. Heat pipes 110 are in the spaces formed next to islands 120. In an embodiment, islands 120 are configured to be in areas corresponding to low power densities of an electrical component. For example, for a multi-core processor, the heat pipes could be placed directly over the center of the cores of the multi-core processor, while islands 120 could be placed over the area in-between the cores. In an embodiment, load plate 160 is above baseplate 180, above one or more islands 120, and below one or more fins 150, where one or more islands 120 is configured to provide a mechanical load transfer path from load plate 160 to baseplate 180.

Referring to FIG. 2A and FIG. 2B, in an embodiment, the present invention provides a heat dissipation assembly 200 including a baseplate 220 formed out of a thermally conductive metal. For example, baseplate 220 could be formed out of copper, steel, or aluminum. In an embodiment, baseplate 220 is formed with cut-outs designed to fit heat pipes 210 and vapor chambers 240 inside the cut-outs. In an embodiment, baseplate 220 has one or more cut-outs, and one or more heat pipes 210 is embedded in the one or more cut-outs, where the walls of the one or more cut-outs form one or more islands 250. FIG. 2B is a cross sectional view of FIG. 2A taken at cross section line 5. In an embodiment, one or more heat pipes 210 fits entirely in the cut-outs, and vapor chamber 240 fits partially in the cut-outs. In an alternative embodiment, heat pipes 210 fit partially in the cut-outs. In an embodiment, baseplate 220 is machined to form the cut-outs. The areas next to the cut-outs are islands 250 configured to take compressive force applied to them by a load plate 230. In one example load plate 230 is pulled down at each end by spring structures and load screws. For example, load plate 230 therefore could apply pressure to the area of baseplate 220 in-between heat pipes 210. To accomplish this, the cut-outs for heat pipes 210 could be slightly larger than heat pipes 210. This would allow for a small clearance between load plate 230 and heat pipes 210 and no clearance between load plate 230 and baseplate 220.

Referring to FIG. 3, in an embodiment, the present invention provides a method 300 of fabricating a heat dissipating device including a step 310 of positioning one or more heat pipes onto a baseplate, where the one or more heat pipes is in thermal communication with the baseplate, where the one or more heat pipes has one or more internal cavities, a step 320 of attaching one or more vapor chambers to the one or more heat pipes, where the one or more vapor chambers has one or more internal cavities, where the one or more internal cavities of the one or more heat pipes is contiguous to the one or more internal cavities of the one or more vapor chambers, where the one or more vapor chambers extends from the one or more heat pipes, a step 330 of putting fluid in the heat dissipation cavities, and a step 340 of attaching one or more heat conducting fins to the one or more vapor chambers, where the one or more heat conducting fins extends from the one or more vapor chambers.

In an embodiment, method 300 further includes forming the baseplate with cut-outs to accommodate the one or more heat pipes, and installing the one or more heat pipes in the one or more cut-outs, where the walls of the one or more cut-outs form one or more islands. In an embodiment, the one or more fins is soldered, along a bent side edge of the one or more fins, to one or more flat portions of the one or more vapor chambers. In a further embodiment, method 300 includes installing a load plate above the baseplate, above the one or more islands, and below the one or more fins, where the one or more islands is configured to take pressure applied to it via the load plate.

In an embodiment, the method further includes hermetically attaching at least one of one or more heat pipes 110 to at least one of one or more vapor chambers 130 and 170, thereby cooperatively forming at least one sealed chamber.

In an embodiment, the method further includes positioning one or more heat pipes 110 according to a power density of one or more electronic components. In an alternative embodiment, the method includes positioning the one or more heat pipes according to a power density of a target electrical component. For example, heat pipe assembly 100 could be designed so the heat pipes are directly over an area 190 with the highest heat density.

Referring to FIG. 4, in an exemplary embodiment, the present invention provides a method 400 of dissipating heat from an electronic component including a step 410 of positioning one or more heat pipes onto a baseplate, where the one or more heat pipes is in thermal communication with the baseplate, where the one or more heat pipes has one or more internal cavities, a step 420 of attaching one or more vapor chambers to the one or more heat pipes, where the one or more vapor chambers has one or more internal cavities, where the one or more internal cavities of the one or more heat pipes is contiguous to the one or more internal cavities of the one or more vapor chambers (heat dissipation cavities), where the one or more vapor chambers extends from the one or more heat pipes, a step 430 of attaching one or more heat conducting fins to the one or more vapor chambers, where the one or more heat conducing fins extends from the one or more vapor chambers, a step 440 of putting fluid in the heat dissipation cavities, a step 450 of installing the baseplate onto an electronic component, operation 460 of applying pressure to the electronic component through the baseplate, a step 470 of evaporating the fluid at an inner surface of the one or more heat pipes, and a step 480 of condensing the fluid at an inner surface of the one or more vapor chambers. In a further embodiment, the angle made by the one or more heat pipes and one of the one or more vapor chambers is any suitable angle. In a further embodiment, the angle made by one of the one or more fins and one of the one or more vapor chambers is any suitable angle. For example, the angle made by the one or more heat pipes and one of the one or more vapor chambers is between 45 and 135 degrees. In a further embodiment, the angle made by one of the one or more fins and one of the one or more vapor chambers is between 45 and 135 degrees.

In a further embodiment, method 400 includes forming the baseplate with cut-outs to accommodate the one or more heat pipes, where one or more solid material islands is formed between the one or more cut-outs, where the one or more islands is configured to take pressure applied to it, and installing a load plate above the baseplate, above the one or more islands, and below the one or more fins, where the one or more islands is configured to take pressure applied to it via the load plate.

In an embodiment, the heat pipes are round. In an embodiment, the heat pipes are rectangular. In an embodiment, the heat pipes have at least one flat surface. In an embodiment, the heat pipes may be any size or shape. For example, rectangular heat pipes or heat pipes with at least one flat surface could have a larger surface area engaged or nearly engaged to the baseplate. A highly conductive thermal interface material could increase the thermal conductivity, but the thermal conductivity could still be limited by the surface area at the interface. In an embodiment, a shaped heat pipe is used to increase the surface area at the interface. The heat pipe could be formed with a rectangular cross section. One of the flat surfaces could be bonded to the baseplate, thereby significantly increasing the surface area of the heat pipe in communication with the baseplate. In a further embodiment, the rectangular cross section has rounded edges. In an alternative embodiment, the cross section of the heat pipe is substantially round cross section with one or more flattened sides. In one embodiment, the method includes soldering the one or more fins, along a bent side edge of the one or more fins, to one or more flat portions of the one or more vapor chambers.

In an embodiment, the one or more heat pipes is in thermal communication with the baseplate through soldering, brazing, or using a highly conductive thermal interface material. For example, thermal communication could mean, thermally coupled to, thermally in contact with, or any other method of joining two parts that facilitates thermal conduction between the two parts. In an embodiment, the heat pipes are attached using a thermally conductive paste.

In an embodiment, two or more heat pipes are used, and all heat pipes have the same thermal characteristics. In an embodiment, two or more heat pipes are used, and at least one of the heat pipes has different thermal characteristics from the other heat pipes. Thermal characteristics relate to the rate at which heat could be removed by the heat pipe. Thermal characteristics could be tied to one or more properties of the heat pipes. Thermal characteristics could relate to one or more of the following: (i) the material to make the heat pipe and or the vapor chamber, (ii) the material used to make the wick, (iii) the design of the wick, (iv) the type of the wick, (v) the fluid used in the heat pipe and vapor chamber, (vi) the size of the heat pipe, and (vii) the design of the heat pipe.

In an embodiment, the contiguous internal cavities are open to each other. Fluid or vapor could move from the internal cavity of the heat pipe to the internal cavity of the vapor chamber, and fluid could move from the internal cavity of the vapor chamber to the internal cavity of the heat pipe. In one embodiment, internal cavity of the heat pipe and the internal cavity of the vapor chamber are interconnected. In one embodiment, the contiguous vapor chambers are hermetically sealed.

In an embodiment, the heat pipes could be positioned in any suitable manner. In an embodiment, the one or more heat pipes is able to be positioned according to a power density of one or more electrical components. The one or more heat pipes could be positioned to better cool the one or more electrical components. For example, if one of the one or more electrical components may have the highest power density, a heat pipe could be positioned to directly cover, and thereby more effectively cool, the component with the highest power density. In a further embodiment, a low power density component of the one or more components may not need a heat pipe positioned to cover the low power density component. For example, the low power density component may not produce enough heat to need a heat pipe positioned directly over it. In an alternative embodiment, heat pipes with different thermal characteristics are positioned according to the power density of the one or more components. For example, the heat pipes with the highest heat transfer coefficient could be positioned over the electrical component with the highest power density, and the heat pipe with the lowest heat transfer coefficient could be positioned over the component with the lowest power density.

In an embodiment, an arrangement with two or more heat pipes could still be able to function if one heat pipe became effectively inoperable or non-functioning. For example, if the pressure buildup in the system were to reach a critical point, a heat pipe could fail (e.g., balloon or bulge out, thereby separating the heat pipe from the baseplate). Ballooning may exacerbate the issue by limiting the effectiveness of the heat pipe or vapor chamber, thereby causing pressure to build up even more. In an embodiment, multiple heat pipes could limit the problem caused by a single heat pipe. If one heat pipe were to fail, the other heat pipes in the system could still operate and provide cooling to the device. In another example, if pressure were applied directly to the heat pipes, the heat pipes could be crushed, thereby limiting the flow through the heat pipes.

In an embodiment, an internal cavity of the vapor chamber is interconnected to an internal cavity of the heat pipe. For example, such an interconnection could allow for liquid vapor produced in the heat pipe to travel to the vapor chamber where could condenses on the internal walls of the vapor chamber. Further, for example, the liquid could then travel to the heat pipe through capillary action, gravity, or centrifugal force, where the liquid could be vaporized again.

In an embodiment, the vapor chamber is substantially rectangular in shape. In an embodiment, the one or more vapor chambers has a substantially rectangular cross section. The vapor chamber is where the majority of the vapor, produced by the one or more heat pipes, condenses. In an embodiment, the vapor chamber has support posts positioned at one or more strategic structural support points throughout the internal cavity.

In an embodiment, one or more fins are attached to the largest flat portions of the vapor chambers. In an embodiment, the fins have bent ends at the attachment edge where the fins are attached to the vapor chamber. The flat side of the vapor chamber could be securely bonded to the bent ends of the fins. This method of bonding is more secure that bonding round heat pipes to copper fins. The fins are made of a material with a high thermal conductivity. For example, the fins may be made of copper.

In an embodiment, the material and fluid of the heat pipe are selected to fit the desired application. In an embodiment, the material and fluid is selected from a group of copper and water working fluid, copper and Refrigerant R134a working fluid, steel and refrigerant R134a working fluid, aluminum and ammonia working fluid, super alloy, and alkali metal working fluid.
